Really want to remove my location and didn't mean to update it. Sorry

I've cleared it for you.

If you're on a mobile, scroll right down and tap the button for the full version of the site.

Click on your name, above your avatar, it will take you to your profile page. On the top right of this page is a button labeled 'edit my profile'. You can make any changes you want there.

I don't think that it's set up to take an empty box for location, so that might have been stopping you from clearing it.
